Form 26AS Corrections

My Bankers made following  mistakes in the 26AS for AY 2020: INTEREST ON A FD PAID TO SB ACC ON 31/12/2019.  TDS COLLECTED ON THAT INTEREST COLLECTED FROM SB ON 1ST Jan 2020. Upto this there is no issue . In the 26AS under Part A : Sr. No.1 the above Interest paid and TDS details appeared. Again additional entry under Sr.2 FD Interest paid entry appeared by mistake of the staff. For which there is no TDS Deducted. I am not entitled for this entry. It is totally mistake by bank staff. Again, Under PART A1 TDS EXEMPTION UNDER 15G/H in 26AS there was another mistake by bank staff, (I am not entitled for 15H also) for exemption of TDS on FD interest made by the banker without my knowledge and without obtaining any declaration  from me. The both the erroneous  entries appeared in 26 AS and included in the total interest income. I have informed  the bankers also to correct the mistakes in the F-26AS  But bankers are not responded to my queries. What further steps to be taken by me.
